Abstract
The invention provides an ink jet head capable of forming a color image with a high image quality. A plurality of nozzle arrays consisting of a large number of ink nozzles include first nozzle arrays ejecting a large quantity of ink drops and second nozzle arrays ejecting a small quantity of ink drops. When the plurality of nozzle arrays eject ink drops simultaneously in parallel, an air flow is generated in the ejecting direction but since the first nozzle arrays are located on the opposite sides of the second nozzle arrays in the main scanning direction, the air flow generated by a large quantity of ink drops is not shifted to the small quantity of ink drops to have an effect thereon. Since the large amount nozzle arrays are disposed at first columns and the small amount nozzle arrays are disposed at second columns on both sides of the shifting directions along the main scan direction, the deflection of the ink droplet caused by the first air flows is totally reduced.

The specific embodiment
(formation of form of implementation)
Below with reference to Fig. 1～Fig. 5 an embodiment of the present invention is described.As shown in Figure 1, the ink gun 100 of this form forms the re alphapro type corresponding with panchromatic printing, is arranged along main scanning direction by 10 nozzle arrays 102 that are listed as that a plurality of ink nozzles 101 of arranging along sub scanning direction respectively constitute.
Say in more detail, in the ink gun 100 of this form, the nozzle arrays 102 of 10 row constitute by spraying respectively as trichromatic YMC (yellow product dark purple) ink droplet D-Y, the M of look, nozzle array 102-Y, the M of C, C, nozzle array 102-Y, the M that these YMC use, C with Y with being center arrangement symmetrically on main scanning direction.
In addition, in the ink gun 100 of this form, the nozzle arrays 102 of 10 row are made of a plurality of a large amount of nozzle array 102-L of the ink droplet D-L of the 1st liquid measure of spraying regulation, a plurality of a small amount of nozzle array 102-S of spraying the ink droplet D-S of the 2nd liquid measure of lacking than the 1st liquid measure.
For example, the 1st liquid measure of ink droplet D-L is made of " 5 (pl:pico-liter) ", and the 2nd liquid measure of ink droplet D-S is made of " (pl) ".Like this,, the 1st liquid measure is called " in a large number ", the 2nd liquid measure is called " on a small quantity " for simplified illustration below.
Say that more specifically nozzle array 102-C, the M that this C uses and M uses is made of a large amount of nozzle array 102-CL, ML and a small amount of nozzle array 102-CS, MS, but the nozzle array 102-Y that Y uses only is made of a small amount of nozzle array 102-YS.
For this reason, at the ink gun 100 of this form, make a large amount of nozzle array 102-L be positioned at least the 1 row of the moving direction on the main scanning direction, simultaneously, a small amount of nozzle array 102-S is positioned at the 2nd row.The ink nozzle 101-L that sprays a large amount of ink droplet D-L for example forms the circle of diameter " 16 (μ m) ", and the ink nozzle 101-S that sprays small volume of ink water droplet D-S for example forms the circle of diameter " 10 (μ m) ".
In addition, nozzle array 102-Y, the M that YMC uses, C arrange on main scanning direction symmetrically, but its ink droplet D is homochromy, in (among the figure) left side of same diameter and nozzle array 102-(1), (2) on right side, the cycle of the arrangement of ink nozzle 101, " T " was identical, and phase place is opposite by half period amount " t (=T/S) ".
In YMC, make that for MC be size, only be greatly for Y, so, compare with by deep or light formation image the time, can reduce the amount of squeezing into of drop.Particularly be 1pl by the amount of dripping that makes droplet, even be easy to occasion that image quality is exerted an influence most in the difference of drop amount, equal image quality in the time of also can realizing with deep or light the use.
In the ink gun 100 of this form, at each nozzle array 102 by " 600 (dpi: point/inch) " arrangement, so, be about 42 (μ m) in the arrangement cycle " T " of the ink nozzle 101 of each nozzle array 102.
In addition, in the ink gun 100 of this form, the arrangement pitch of the arrangement pitch of nozzle array 102-L and a small amount of nozzle array 102-S is that " 1.376 (mm): the arrangement pitch of the homochromy nozzle array 102 of adjacency is " 0.254 (mm): at this moment, dispose ink supply port 111 between homochromy a large amount of nozzle array 102-L of adjacency and a small amount of nozzle array 102-S in a large number.
That is, with the corresponding a large amount of ink nozzle 101-L of same ink supply port 111 and the relative main scanning direction of small volume of ink nozzle 101-S by the cycle approximately " 21 (μ m) " be arranged in staggered.In addition, a small amount of nozzle 101-S of a small amount of nozzle array 102-S is held on the configuration of a large amount of ink nozzle 101-L ground on two directions of main scanning direction.
The ink gun 100 of this form like that, has orifice plate 104 and silicon substrate 105 shown in Fig. 2 B, they carry out stacked.Ink nozzle 101 is formed at orifice plate 104, and the homochromy nozzle array 102 of each adjacency is communicated with integratedly in the inside of orifice plate 104.
Silicon substrate 105 is for example by＜100〉silicon constitutes, and like that, on its surface the position of each ink nozzle 101 formed heater element 107 as ink jet device shown in Fig. 2 A.This heater element 107 sprays ink droplet D by making the ink foaming from ink nozzle 101.
But, as described above, there is size at ink nozzle 101, so, form the heater element 107-L of the 1st area of " 26 * 26 (μ m) " in the position corresponding, form the heater element 107-S of the 2nd area of " 22 * 22 (μ m) " in the position corresponding with the ink nozzle 101-S of minor diameter with large diameter ink nozzle 101-L.
These heater elements 107 form drive circuit 108 along the main scanning direction adjoining position, connect heater element 107 with these drive circuit 108 adjacency.In addition, form a plurality of splicing ears 109, connect drive circuits 108 at its splicing ear 109 in the position nearby, two ends of the sub scanning direction on the surface of silicon substrate 105.
At silicon substrate 105, to the homochromy nozzle array 102 formation providing ink passages 111 of each adjacency, so like that, this providing ink passage 111 is communicated to the homochromy nozzle array 102 of adjacency in the same manner shown in Fig. 2 B.This providing ink passage 111 is formed at by＜100 by anisotropic etch〉silicon substrate 105 that constitutes of silicon, so its section configuration is trapezoidal.
As Fig. 3 and shown in Figure 5, the ink gun 100 of this form forms as the part of ink-jet printer 200, and is such as shown in Figure 4 and Figure 5, is equipped on the walking carriage 201 of the ink-jet printer 200 of this form.
Say that in more detail as shown in Figure 3, the ink gun 100 of this form is installed on ink cartridge 202, as shown in Figure 5, this ink cartridge 202 is installed on walking carriage 201.Walking carriage 201 can be freely ink cartridge 202-Y, the M, the C that use of installation YMC with installing and removing, from these ink cartridges 202-Y, M, C the ink of YMC look is supplied to nozzle array 102-Y, M, the C that the YMC of ink gun 100 uses respectively.
In addition, as shown in Figure 4, the ink-jet printer 200 of this form has main scanning mechanism 204 and subscan mechanism 205, main scanning mechanism 204 can move freely ground supporting walking carriage 201 towards main scanning direction, and subscan mechanism 205 makes in the position with ink gun 100 face-offs and is printed medium P and moves towards sub scanning direction.
In addition, the ink-jet printer 200 of this form has the unified control circuit (not shown) that is made of microcomputer and drive circuit etc., unifies the action of the unified control of control circuit ink gun 100, main scanning mechanism 204, subscan mechanism 205 by this.
In formation as described above, the ink-jet printer 200 of this form can form coloured image on the surface that is printed medium P.In this occasion, make by subscan mechanism 205 to be printed medium P and to move at sub scanning direction, simultaneously, ink gun 100 is moved back and forth at main scanning direction by main scanning mechanism 204.At this moment, from the ink nozzle 101 of ink gun 100 ink droplet D is ejected into and is printed medium P,, thereby form the coloured image of dot matrix so this ink droplet D is attached to and is printed medium P.
The ink-jet printer 200 of this form can freely be set a plurality of patterns with switching, implements various printing actions corresponding to its pattern.For example, under high quality mode, when ink gun 100 moves back and forth, make all nozzle array 102 work toward road and multiple road both sides on main scanning direction at it as its basic model.
The ink gun 100 of this form as shown in Figure 1, ink droplet D as described above be homochromy, with the left side and nozzle array 102-(1), (2) on right side in footpath, the arrangement cycle " T " of ink nozzle 101 is identical, phase place by half period amount " t " on the contrary.For this reason, as described above,, on sub scanning direction, be printed the pixel that medium P arrangement is formed by ink droplet D by the cycle " t " by making all nozzle array 102 work simultaneously.
In addition, the ink-jet printer 200 of this form becomes the secondary look by the plain density artificially generated terrain of example of regulating the YMC look, but the ink gun 100 of this form selectively sprays a large amount of ink droplet D-L and a spot of ink droplet D-S of M look and C look.For this reason, can freely form the pixel of the size of M look and C look, so, the density of the pixel of the secondary look that artificially generated terrain becomes can be improved.
At this moment, the value that is printed the some footpath on the medium P of a large amount of ink droplet D-L and a spot of ink droplet D-S on average respectively about 48 μ m with interior and about 36 μ m in.
Though the Y look only sprays a spot of ink droplet D-S, because the Y look is near the white that is printed medium P, so the necessity that need form big or small pixel is low.
When in a small amount ink droplet D-S realized more high image quality, as estimation, about 20 μ m were suitable in the some footpath.This is because consider that from the viewpoint of pixel distinguishing about 20 μ m reach lower limit in a footpath.When supposition was driven on the paper of stain rate about 2%, it is suitable that this and emitted dose are about about 0.5pl.
In addition, as the combination of little ink droplet D-S and big ink droplet D-L, a large amount of for the integral multiples more than 2 times in a small amount favourable to realizing high gray scale.
In a plurality of patterns, under fast mode ink gun 100 when main scanning direction moves back and forth, at it toward road and the only a large amount of nozzle array 102-L work of multiple road both sides.In this occasion, a plurality of a large amount of nozzle array 102-L preferably are not subjected to the interference ground that the air-flow of the moving direction of mutual ink droplet D produces and increase nozzle array respectively at interval.That is, as a large amount of nozzle array 102-Ls corresponding with same providing ink passage 111 and the configuration sequence of a small amount of nozzle array 102-S, this form that has a large amount of nozzle array 102-L at the main scanning direction front side is more satisfactory.
The influence of air-flow here, is described according to Fig. 6.
In the ink gun 100 of this form, as the front illustrated, a large amount of nozzle array 102-L were positioned at the 1st row of the moving direction on the main scanning direction, simultaneously, a small amount of nozzle array 102-S is positioned at the 2nd row, and a large amount of nozzle array 102-L also are positioned at the 3rd row of the moving direction of main scanning direction.That is, a small amount of nozzle array 102-S of the 2nd row becomes the formation that a large amount of nozzle array 102-L are positioned at the both sides of main scanning direction.
In such formation, as shown in Figure 6, at the air-flow of the both sides of a small amount of nozzle array generation by a large amount of nozzle arrays generations.This air-flow exerts an influence to the accuracy of spray of a small amount of nozzle, but compares with the occasion that exists at a small amount of nozzle, as is present in both sides, then is subjected to the influence of each air-flow, so droplet is not one-sided, and is also stable as image.
In addition, in the occasion that uses droplet ejection, compare with big injection, there is the tendency of main relatively mist amount increase of dripping, but what take place when this uses droplet ejection swims mist under the influence of the air-flow of a big nozzle of the both sides of droplet nozzle, also can be as shown in Figure 6 towards the ink gun side shifting.
In this form of implementation, owing to become the formation that disposes a large amount of nozzle arrays in the both sides of all a small amount of nozzle arrays, so, can carry out the printing of high image quality.
(variation of form of implementation)
The invention is not restricted to above-mentioned form, permitted various distortion at the range content that does not break away from its main idea.For example, in above-mentioned form, owing to be to the little Y look of image quality influence, so, only form a large amount of nozzle array 102-YL (1), YL (2), thereby example illustrates the occasion of the structure of simplifying ink gun 100, but as the illustrative ink gun 120 of Fig. 7, also can be at a large amount of nozzle array 102-L of whole formation that YMC uses (1), L (2) and a small amount of nozzle array 102-S (1), S (2).
In addition, in above-mentioned form, example is illustrated in the occasion that ink gun 100 forms the nozzle array 102 that YMC use, and in addition, also can append the nozzle array 102 of K (black) usefulness, also can form the nozzle array 102 (all not shown) that the look beyond the YMC is used.
Equally, in above-mentioned form, example illustrates the occasion of the ink gun 100 that the YMC that only carries ink-jet printer 200 uses, but also can carry the ink gun that K uses, and also can carry the ink gun (all not illustrating in the drawings) that the color beyond the YMC is used.
In addition, in above-mentioned form, example illustrates the occasion that makes all nozzle array 102 work when ink-jet printer 200 when main scanning direction moves back and forth ink gun 100 often, but for example in Fig. 1, make ink gun 100 when move on the right side, only make nozzle array 102-(1) work on right side, when the present dynasty left side is mobile, also can only make nozzle array 102-(2) work in left side.
In addition, in above-mentioned form, example be illustrated in ink gun 100 along main scanning direction arrange nozzle array 102 symmetrically, in the occasion that both sides make ink gun 100 work that moves back and forth of main scanning direction, but for example also can be only in the work when move on the right side of the ink gun (not shown) of the structure of the right-hand part that makes Fig. 1.
In addition, in above-mentioned form, example illustrates by anisotropic etch＜100〉thus the silicon substrate 105 that silicon constitutes forms providing ink passage 111 forms trapezoidal occasion with its section configuration.Yet, also can be as the illustrative ink gun 130 of Fig. 8, by anisotropic etch＜100 thereby the silicon substrate 131 that silicon constitutes forms providing ink passage 132 forms linearity with its section configuration.In addition, also can form the providing ink passage, thereby the providing ink tunnel-shaped be become linearity with the face orientation-independent ground of silicon substrate by Laser Processing or sandblast rather than anisotropic etch.
In addition, in above-mentioned form, example illustrates for the ink droplet D that sprays size nozzle array 102-L, the S of combined size and the heater element 107-L of size, the occasion of S, but be not impossible for example at heater element 107-L, the S of nozzle array 102 combined size of certain size or at the heater element 107 of the nozzle array 102 combination certain sizes of size.
In addition, in above-mentioned form, as the ink jet device example of spraying ink droplet D heater element 107 is shown, but also can be the vibrating elements (not shown) from ink nozzle 101.In addition, in above-mentioned form, example illustrates various numerical value particularly, but certain illustrative numerical value can change over multiple.
As described above, in ink gun of the present invention, by on the moving direction of main scanning direction, disposing a large amount of nozzle arrays in the both sides of a small amount of nozzle array, thereby the deflection of the injection direction of the ink droplet that is caused by air-flow is alleviated, can reduce the relative displacement of the eject position of the ink droplet that sprays from a plurality of nozzle arrays, improve the image quality of print image.
And the ink gun 100 of this form selectively uses a large amount of ink droplet D-L and a spot of ink droplet D-S when forming coloured image, so, can improve the density of pixel of secondary look of the image of formation, its image quality is good.Because for the few Y look of the influence of image quality only being formed the occasion of a large amount of nozzle array 102-YL (1), YL (2), its simple structure can realize the raising of miniaturization and and productivity ratio.
In addition, the ink gun 100 of this form is respectively arranged the homochromy nozzle array 102 of 2 row, but jointly is communicated with 1 providing ink passage 111 respectively at the homochromy nozzle array 102 of these 2 row.For this reason, the number of providing ink passage 111 is cut down, the simple structure of ink gun 100, and productivity ratio improves.
